ABB Combustion Engineering Nuclear Fuel (ABB C-E) has completed a qualification program for the use of Er[sub 2]O[sub 3] as a burnable absorber in pressurized water reactors. Neutronic properties and performance have been assessed in a development program that included the following: 1. evaluation and processing of basic cross-section data for naturally occurring erbium isotopes and capture/decay products of erbium and thulium; 2. performance of critical experiments by ABB C-E, Rensselaer Polytechnic Institute, and Southern California Edison (SCE); 3. comparison of methods between ABB C-E and SCE (Ref. 6); and 4. irradiation of lead test fuel assemblies (LTAs) and corefollow analyses in collaboration between ABB C-E and SCE (16 x 16 fuel) and Baltimore Gas Electric Company (14 x 14 fuel). The subject of this paper is the physics core-follow results for San Onofre unit 2.
